public class HybridQuery<T,S> extends BaseEmbeddedQuery<T>
A non-indexed query performed on top of the results returned by another query (usually a Lucene based query). This mechanism is used to implement hybrid two-stage queries that perform an index query using a partial query using only the indexed fields and then filter the result again in memory with the full filter.
